The two rams are held together in parallel relation by meansof .bolt 81 which slides in the opening 30 of the rain 30, and passes its arm 10 byfthe rock shaft and thereby "moves the ram 28 up and down, theup and down movement of the latter, however, being delayed by means of the friction plates 52 which engage the opposite sides .of the enlargement upon the fulcrunied end of the arm 38 so thatthe I ram 28 is only moved as the screw 31 engages the ends of the slot 30. It'will be seen from Fig. 1 that the arm 38' is journaled'on shaft 39' between the plates 1 [52 which, though fixed to prevent theirrotationgare' adjustable towards each other by means of the nut'54t holding them together soas to causeasuitable drag or friction upon the arm 38Hwhich tends'to retard the move 7 ment of the'ram 28 in the upward and downaward movements; of the ram 30', the purpose: of which will presently appearfi The rock.

The rams 28 and '30-are shown in Fig. at

their lower position, free and clear of the rotating receiver 36 which isturned a step at a time between each up-stroke of the ram by means (not shown) such as disclosed in a j my pending application, which imparts a step-by-step'rotation to the receiver; When the ram 30 starts up, it first advances beyond the end of the ram 28 as from. the position shown in Fig. 6 to that shown in Fig. 7 the arms 12 by reason of their contact with the member 26 having lifted the center seizer 12 sothat the package is free along its central person" (see Fig.-

The band feeding mechanism shown the; drawings is adapted to feed the bands from a stack of the same contained in a reservoirin which the bands gravitate andre'st upon the inturned shelves 71 at the bottom of the reservoir. The reservoir is suitably held in a fixed but adjustablepositio-n. The top of the stack of bands is pressed upon'by means of two weights'73 which bear upon the stack and force the stack downwardly and against the inturned shelves 71. 'One --ed-ge 0f the needle or pricker 7-4 adjustably held in a bracket aflixed to the reservoir. This pricker'74 by reason of the weight 73 overlymg the pri'cker 74 and also the weight of the stack .of bands in the reservoir .perforates two or perhaps three ofthe lowermost bands in the stack. By this means the lowermost band :can be pushed fromthe bottom of the stack so ithatit can be separated from the same i by the pincers hereinafter described without displacing "the adjacent overlying band.v Tflie separation of the lowermost'band from the stack .isaccomplished by means o-f'a pair ofx-friction' members-or fingers .7 6, pref-v erably made ofzrubber, the reciprocatinggmomost bandbyltearing it away from theirn'paling pricker.
